The structure has structural gaps 101 formed between adjacent structures 100, and when a safety accident such as collapse occurs, the structural gaps 101 are the positions where the spatial displacement and the force variation are first reflected.
The Beidou monitor 103 is connected to the structural body 100 and is positioned outside the structural gap 101; the Beidou monitor 103 is movably connected with a moving ring 106 which moves up and down elastically relative to the structural body 100, and when the Beidou monitor 103 is spatially displaced, the moving ring 106 also moves relatively. The side edge of the movable ring 106 extends outwards to form a connecting strip 104, the connecting strip 104 is provided with an end face facing the structural body 100, and two elastic bodies are arranged on the end face facing downwards; the sensor comprises a pressure sensor 105, and the elastic body is provided with the pressure sensor 105; the connecting strip 104 spans the structural gap 101, and the two pressure sensors 105 each abut against two adjacently arranged structures 100.
By the abutment of the two pressure sensors 105 against the two adjacent structures 100, when there is no relative displacement between the two structures 100, the pressure values of the pressure sensors 105 are uniform, and when there is a spatial displacement between the two structures 100, the pressure values of the two pressure sensors 105 change due to the elastic movement of the elastic body, which is arranged on the pre-pressed elastic body, which drives the position change of the pressure sensors 105, when the spatial displacement between the two structures 100 occurs.
When the pressure value changes beyond the set value range, the background control center combines the pressure value and the monitored data of the Beidou monitor 103 to judge whether the event is an abnormal event.
Because the Beidou monitor 103 also changes in displacement when the structural body 100 is spatially displaced, the movable ring 106 is movably arranged on the Beidou monitor 103, and the influence of the displacement change of the Beidou monitor 103 on the pressure monitoring of the two pressure sensors 105 can be eliminated.
The elastic body is in a pre-pressed state, so that the pressure sensor 105 can be ensured to be abutted against the structural body 100 at any time within a limited displacement variation range.
The connecting strip 104 is provided with two mounting grooves which are arranged at intervals towards the end face, the inner end of the elastic body is fixed in the mounting grooves, the outer end of the elastic body extends out of the mounting grooves, and the pressure sensor 105 is arranged at the outer end of the elastic body. Thus, the elastic body can be ensured to have enough elastic change distance to meet the monitoring requirement.
The Beidou monitor 103 is provided with a cylindrical barrel shell, wherein an annular groove is formed in the periphery of the barrel shell, and the annular groove is arranged around the periphery of the barrel shell; the upper portion cover of annular groove is equipped with rubberizing ring 108, and the lower part cover of annular groove is equipped with down gluey ring 107, rubberizing ring 108 and down gluey ring 107 can squeeze the deformation when pressing, and when outside pressure was withdrawn, then can restore to the original state.
The movable ring 106 is sleeved in the middle of the annular groove; the upper end surface of the moving ring 106 is abutted against the bottom of the rubberizing ring 108, and the lower end surface of the moving ring 106 is abutted against the top of the lower rubberizing ring 107; the upper rubber ring 108 and the lower rubber ring 107 are respectively in a pre-pressing deformation state. In this way, when the adjacent structural bodies 100 are displaced, the Beidou monitor 103 moves along with the displacement, so that the movable ring 106 can resist the upper rubber ring 108 or the lower rubber ring 107, thereby buffering the movement of the movable ring 106 and avoiding the influence on the pressure monitoring of the pressure sensor 105 caused by the movement of the movable ring 106 along with the Beidou monitor 103.
When the structure 100 is reset in a non-accident space movement, such as a normal shock, the movable ring 106 is reset under the restoring action of the upper ring or the lower ring 107.
The lower end surface of the movable ring 106 extends towards the periphery to form a flat abutting annular surface 1061, and the abutting annular surface 1061 abuts against the top of the lower rubber ring 107; the bottom of the rubberizing ring 108 is provided with an embedded ring groove, the embedded ring groove is circumferentially arranged along the bottom of the rubberizing ring 108, and the upper end face of the movable ring 106 is embedded in the embedded ring groove.
Since the movable ring 106 has a weight, the movable ring 106 can be stably abutted against the top of the lower rubber ring 107 by providing the lower end surface of the movable ring 106 with a flat abutting end surface. The upper end surface of the movable ring 106 is embedded in the embedded ring groove of the rubberizing ring 108, so that when the movable ring 106 moves upwards relative to the rubberizing ring 108, the movable ring 106 can accurately press the rubberizing ring 108 to deform upwards, and the phenomenon of joint dislocation or uneven pressing force is avoided.
The structure 100 has a structure end face facing the structure slit 101, the structure end face is provided with a guide groove, the outer periphery of the guide groove is circular, the depth of the guide groove gradually decreases along the radial outward extending direction of the guide groove, that is, the guide groove is a circular groove, the depth of the center position of the guide groove is deepest, the depth of the guide groove gradually decreases along the direction facing the edge, and the entire guide groove is tapered.
The sensor comprises a rolling sensor 102 arranged in a structural gap 101, the rolling sensor 102 is in a sphere shape, and the diameter of a guide groove is larger than that of the rolling sensor 102, so that the rolling sensor 102 can roll along the radial direction of the guide groove. The two sides of the rolling sensor 102 are respectively movably embedded in the guide grooves of the two structural bodies 100; when the two structures 100 are displaced, the two guide grooves are displaced relative to each other, and the rolling sensor 102 rolls in the two guide grooves.
In this way, when the misalignment movement occurs between the two structures 100, the misalignment movement may be spatially performed, and the rolling sensor 102 rolls relatively in the misalignment direction upon receiving the abutting action of the structure end faces of the structures 100, so that the misalignment movement direction, movement distance, and the like of the adjacent structures 100 can be determined based on the rolling data of the rolling sensor 102. Of course, according to the rolling data of the rolling sensor 102, in combination with the monitoring data of the Beidou monitor 103, the spatial movement data of the structure body 100 can be accurately determined.
The outer periphery of the rolling sensor 102 is covered with an elastic layer, so that the rolling sensor 102 is ensured not to generate pure rolling phenomenon between the structural end faces of the two structural bodies 100, and the monitoring precision is further affected. When a spatial displacement occurs between the two structures 100, the rolling sensor 102 is inevitably rolling.
The bottom of guide way is equipped with a plurality of sunken positions, and a plurality of sunken positions are arranged along the radial interval of guide way, and arrange around the center of guide way. Thus, after the space movement between the two structures 100 is stopped, the rolling sensor 102 can be fixed at the position through the concave position, so that the rolling sensor can be prevented from being restored to the original position due to slipping, and the intermittent space movement can be conveniently monitored for a plurality of times.
The foregoing description of the preferred embodiment of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
